Hobos were often mentioned in the show, as Dan Schneider has a fixation on them. However, there have been no references to hobos since Season 4 due to complaints about classism.
Only three hobos are actually shown: Hollywood the hobo in iTake On Dingo, a hobo briefly seen in the Wade Collins video in iRocked the Vote, and the picture of a hobo in iLook Alike. The gang (except for Spencer) dressed up as hobos for the hobo party in iEnrage Gibby.
- iWanna Stay With Spencer: When Carly dresses up as a punk, Granddad asks Spencer if her next "phase" will be "stealing cars or swimming with hobos." Spencer answers "I don't think hobos enjoy swimming."
- iPromise Not to Tell: After Carly asks if they can't give her new TV to a hobo, Spencer says that hobos can't afford cable. This sentence (along with her guilty conscience) haunts Carly for the rest of the episode.
- iHatch Chicks: After Spencer quotes "either Einstein or that hobo that sleeps in the garbage behind the building," Sam says she loves hobos and wants to do a science project on them. Sam thinks that they are affected by gravity and she wants to study that for the science project.
- iPromote Techfoots: Spencer says that when he was riding the bus, a hobo spilled chili on him and continued to eat it without a spoon.

- iTake on Dingo: The iCarly trio and Spencer spend two nights at a room in a disgusting motel where the owner said that they have a great view of Hollywood, but it's actually a room where a hobo named Hollywood sleeps outside of the window.
- iMust Have Locker 239: Spencer makes Carly draw hobos for three hours in a park.

2) Freddie's card's word in the game "What Am I?" is hobo at the end of the episode during the second time Spencer and Freddie switch to new "What Am I?" cards.
